Rock Island Z21CS Z-Series CS 9mm Luger 3.98″ 16+1 Black Nitride Frame with Rail Black Nitride Steel Slide Black Polymer Grip

The Z21 CS sports similarities to the barrel lock up of most modern pistols where its barrel and slide are locked together until the barrel is cammed down by a block. You can choose between a cocked and locked capability to use a single action trigger system or a double action trigger system. It has great ergonomics, safety decocker, a good sight attached and finishes off with a frame to slide and barrel fit.
